Dr. Christopher J. Herron

I was born in Iran, moved to Germany at age 18 for college, and have lived in the United States since 1992. I’ve always been close to my parents, brothers and sister. Our relationship gave me a sense of respect for the concept of family that is reflected in the way I treat patients and families today. My interest in cardiology began when I was just eight or nine years old reading a schoolbook about heart function; I decided then and there on my career. I chose to work with children because of their great need and limited ability to express themselves. It’s rewarding to connect and understand what they’re trying to say. Because children are very delicate, I insist on precision with every service I provide. I’m also passionate about getting the diagnosis right. Sometimes parents bring their child to me after multiple doctors have given up trying to diagnose them. I like the challenge and the opportunity to provide treatment that will help. Many of my patients — for example, kids with congenital heart conditions — must be treated over a period of months or even years. I try to really manage their condition and help their family be part of the care team. I’m also interested in providing medicine that has been lacking in Florida. Dysautonomia, a nervous system disorder, is one of them. Dr. Kakavand is highly rated in 38 conditions, according to our data.
